b. Starting with the release of V3_51_359, DVX utilizes an intelligent download feature that will skip any part of the DVX device firmware that has the same version as the firmware already loaded in the system. For example, the FGPA portion of the firmware will be skipped if there are no changes to it in the new release being uploaded. This in enabled by default. While it should not be necessary, the user can change the intelligent downloading settings by using the following telnet command in superuser mode:smart-downloading [enable|disable|status]

Changes in this release:

New Fixes:

Added ACK/NAK processes for sending and receiving messages with the master. This will allow us to be able to detect and resend corrupted messages

Accumulated Fixes from previous Hotfixes:

v1.4.33

Fixed VIDOUT_ON-ENABLE/DISABLE to enable and disable video on the correct output port.

Switching audio inputs with global mute on and a microphone input enabled will now keep audio muted through the switch.

v1.4.32

Fixed issue where switching from a high-resolution DVI input to an input with nothing connected would leave a frozen image.

Modified the operation of input gain mute (channel 143) such that changes to the associated gain level do not cause it to unmute.

Corrected an issue where the gain mute setting was not being retained for each input when switching audio.

Fixed an issue where values sent to LEVEL 1 were being returned 2-3 units lower.

Added the resolution 1280x800@60Hz to the default EDID table sent to connected VGA/DVI sources.

Fixed issue where the switch would appear to accept a message from the NI controller yet would not perform the task. This was due improper handling of an internal exception which caused the video task to hang.
